Specific Embodiments

[0022] The accompanying drawings are specific embodiments of the present utility model.

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0024] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0025] As Figures 1 to 6 shown, this ultrafiltration membrane device cleaning device includes a conical tank body 1. The conical tank body 1 can be supported by 3 - 4 support feet 2. The lower end of the conical tank body 1 is a relatively small plane. On this plane, a water outlet pipe 3 is installed. The water outlet pipe 3 is connected to a circulation pump 4, and the circulation pump 4 is connected to a water return pipe 5. An electric motor 6 is also installed on this plane. The output end of the electric motor 6 faces upward and is fixedly connected to a rotating shaft 7. The rotating shaft 7 is rotationally connected to this plane in a sealed manner. After passing through this plane, the rotating shaft 7 extends into the conical tank body 1, and then its upper end is fixed on a mounting plate 8. The mounting plate 8 is of a hollow structure, and the periphery of the mounting plate 8 is rotationally connected to the inner wall of the conical tank body 1.

[0026] A filter screen 9 is installed on the upper surface or below the mounting plate 8.

[0027] Two guide grooves 10 are symmetrically installed in the conical tank body 1. A buffer device 11, such as a spring, etc., is installed inside the guide grooves 10. The lower ends of the two upright portions 13 of an arch-shaped frame 12 are respectively inserted into these two guide grooves 10. A rack 14 is installed on each upright portion 13. The rack 14 is located outside the guide grooves 10. A gear 15 is fixedly installed on the upright portion 13. The gear 15 is meshed with the rack 14. The gear 15 is coaxially connected to a ratchet 16. The two ends of a handle 17 are respectively rotationally connected to the two gears 15 coaxially. The connection between the handle 17 and the gear 15 is like the freewheel of a bicycle. The handle 17 can only drive the gear 15 to rotate in one direction, that is, drive the rack 14 to rise. A pawl 161 matching the ratchet 16 is installed on the guide groove 10.

[0028] In order to ensure synchronism, an arch-shaped sleeve 171 can be provided for the two handles 17, which is put on when rising and taken off when descending.

[0029] A cleaning assembly 18 is installed at the top of the arch frame 12. The cleaning assembly 18 is a prior art and will not be elaborated here. A cylinder 19 is fixed to the lower end of the cleaning assembly 18. The cylinder 19 is cylindrical. The water inlet pipe 20 of the cleaning assembly 18 is located inside the cylinder 19. A positioning groove 21 is correspondingly opened on the mounting plate 8 below each water inlet pipe 20.

[0030] The return pipe 5 is connected to the cleaning assembly 18.

[0031] A through hole 22 is opened on the cylinder 19. Sliding grooves 23 are respectively arranged above and below the through hole 22. The sliding grooves 23 are located on the outer wall of the cylinder 19. A sliding plate 24 is slidably connected in the sliding grooves 23. The sliding plate 24 is an arc-shaped plate with the same curvature as the cylinder 19. A drying mechanism 25 is installed in the middle of the sliding plate 24. When the sliding plate 24 is rotated, the drying mechanism 25 can be aligned with the through hole 22. When the sliding plate 24 is rotated again, the sliding plate 24 can block the through hole 22.

[0032] The drying mechanism 25 can be a heating blower or an ordinary hair dryer. The drying mechanism 25 is preferably installed in a downward inclined manner.

[0033] There is also a circular groove 26 inside the conical trough 1. After the cylinder 19 drops, its bottom enters the circular groove 26.

[0034] The working process is as follows:

[0035] Place the ultrafiltration membrane device on the positioning groove 21, loosen the pawl 161. Under the reaction of the gear 15, the arch frame 12 slowly drops. In order to prevent the arch frame 12 from dropping too fast, the arch frame 12 can also be held to help it drop slowly. After the arch frame 12 drops to the bottom, at this time, the lower end of the cylinder 19 enters the circular groove 26, and the ultrafiltration membrane device is surrounded in the enclosed space inside the cylinder 19. At the same time, the water inlet pipe 20 also inserts into the ultrafiltration membrane device. Due to the existence of the buffer device 11, the water inlet pipe 20 will not cause damage to the ultrafiltration membrane device. At this time, the drying mechanism 25 on the sliding plate 24 leaves the position of the through hole 22, and the sliding plate 24 blocks the through hole 22.

[0036] Turn on the cleaning assembly 18 to clean the ultrafiltration membrane device. The cleaning liquid flows into the ultrafiltration membrane device from the water inlet pipe 20, then flows out of the ultrafiltration membrane device to clean the ultrafiltration membrane device. The cleaned cleaning liquid flows down through the hollow holes of the mounting plate 8, passes through the filter screen 9 and enters the space below the mounting plate 8. Then start the circulation pump 4. The filtered cleaning liquid re-enters the cleaning assembly 18 through the circulation pump 4 and the return pipe 5 to clean the ultrafiltration membrane device until it meets the standard.

[0037] Manipulate the handle 17 to lift the cylinder body 19 so that the cylinder body 19 slightly leaves the conical groove body 1 (which is convenient for forming a flowing air stream, just leaving a little bit. At this time, the water inlet pipe 20 also needs to play a role in stabilizing the ultrafiltration membrane device). Rotate the sliding plate 24 to align the air drying mechanism 25 with the through hole 22, and start the air drying mechanism 25 to dry the cleaned ultrafiltration membrane device. At the same time, start the motor 6, and the motor 6 drives the mounting plate 8 to rotate, and the ultrafiltration membrane device rotates accordingly, so that the air drying mechanism 25 dries the ultrafiltration membrane device in all directions.

[0038] After drying, shake the handle 17 to lift the arched frame 12, so that the cylinder body 19 leaves the conical groove body 1, exposing the ultrafiltration membrane device, and then the ultrafiltration membrane device can be removed.
